Chemical Residues

GIWA regularly collaborates on chemical residue issues with the National Residue Survey (NRS) which is funded by growers and administered by the Federal Department of Agriculture and Water Resources, the APVMA and the National Working Party for Grain Protection (NWPGP) which is funded by GRDC and administered by Grain Trade Australia.

GIWA currently holds one minor use permit which is valid to 31st March 2022, PER84040 for Trifluralin/Pre-Emergent Treatment in Oats for Suppression/Control of Certain Annual Grasses and Broadleaf Weeds on Oats.

GRDC fund a project called “Pesticides for Minor Uses in Grain” which identifies pesticides considered by industry to be essential for continued sustainable production of minor grain crops and then seeks to have them registered or permitted for use.
